Be it known that we, VVILLIAM A. S'rRoTH- ER and WILLIAM" M. STROTHER, citizens of the United States, residing at Lynchburg, in the county of Campbell and State of Virginia, have invented a new and useful Lubricating Compound for the Plates of Tobacco-Presses,

This invention relates to an improved lubricating compound of that class which are used by tobacco-manufacturers to preventthe tobacco from adhering to the metallic pressplates or to the mills; and it has for its object to provide a compound which will not become rancid or produce mold upon the tobacco.

After a long series of experiments and tests we have found that our compound is far supe.

rior in quality and better in results than any lubricating compound of this class. The advantages of our preparation when used on tobacco in the place of oils are obvious. It will never become rancid or produce mold on the tobacco, and when used on the mills it will do more Work and do, it better than any grease 0r lubricating compound ever made.

In using our compound it may be applied directly to the tobacco, to the metallic pressplates, or to any part of the machinery.

The proportions of the above ingredients may be varied according to the state of the weather. In varying the proportions experience will be the only teacher.

Having thus described our invention, we claim and desire to secure by Letters Patent The herein-described compound, consisting of spermaceti, or its equivalents, and petrolatum, or any similar product of petroleum, substantially as stated.
